Alsk Detailed Gravity Survey, NT. (P199226), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Alsk Detailed Gravity Survey, NT. (P199226) contains a total of 1575 point data values acquired at a spacing between 25 and 100 metres. The data is located in NT and were acquired in 1992, under project No. 199226 for None.

重力数据用于测量地球表层下方岩石密度变化所引发的微小重力变动。所采集的数据将通过标准化流程开展处理，以确保记录得到的响应仅源于地下岩石。经处理得到的数据集可通过解译揭示地下地质构造。经处理的数据将由GA地球物理学家开展质量核查，以确保GA发布的最终数据符合使用要求。本次编号为P199226的北领地（NT）Alsk详细重力调查数据集共包含1575个测点数据，测点间距介于25米至100米之间。该数据采集于北领地（NT），于1992年依托编号199226的项目完成采集，委托方信息未明确标注。
